When you save a project, you can save it to a folder on your hard disk drive, a network location, disk, the desktop, or another storage location. To do this, select a desired drive/folder from the Save As window. The Saving process is the same, regardless of what location you choose.
You should save the project frequently while you are working on it to avoid losing data because of an unexpected power failure or other problem.
